The F75/F70 and T2 are all built on the same core platform so check out info on using these from users all over the forums.
Of particular interest to me are how different settings work using the technology, and Tom Dankowski's experimentation and posts about that are spectacular and in my experience actually work.
Once you get by the initial getting to know you stage I would delve into these theories and settings to see exactly what this thing is capable of.
Trash infested sites, iron infested sites, wide open sites, deeper target sites....this thing can do it all once you understand it and exactly what tweaking those settings can do.
There is a language to this thing, both visual on the screen and aural.
Learn that language and the sky is the limit.
A couple of informitive threads here...there are more if you search.
